lRONlNG-BOARD CLAMP.

SPECIFICATION forming part of Letters Patent No. 225,187, dated March 2,1880.

Application filed August 9, 1879.

To all whom it may concern:

Be it known that I, EDWIN W. WARREN, of- Cambridge, in the county ofWashington and State of New York, have invented cer-.

tain new and useful Improvements in Ironing-Board Clamps; and I dohereby, declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of the bottom ofmyironingboard clamp, and Fig. 2 is a perspective view of the same.

My invention relates to an improvement in ironing-board clamps and itconsists in the construction and arrangement of certain parts, as willbe first fully described in the following specification, and nextclearly defined in the claim.

Let A designate an ironing-board, and B a notch or mortise formed in oneend thereof, for the purpose of retaining the clamping device inposition on the board, as presently described, The bed-piece c of theclamping device is provided at its forward end with a block, d, which isadapted to fit into mortise B of the ironingboard, and the said block dis provided with flanges d, which fit into the rabbeted portions 0 ofthe table, alongside of the mortise. These said means maintain theforward end of the bed-piece 0 securely in position, while the rear. endof the same is held firmly to the under side of the ironing-board bymeans of a suitable screw or bolt.

' The lever or clamp-bar e is pivoted to bearings f f, and is. formedwith a slot, 9, at one end, and a fiat cross-piece, h, at the other. Acam-lever, i, is loosely fitted through slot 9, so as to have play fromend to end of the same, and it is formed with a concavity, Z, whichinsures its bearing upon the bed-piece c, and a pin or bolt, m, whichacts upon the clamp-bar when the cam-lever is operated.

N is a spring secured to the bearings f, and arranged to depress thatend of the clamp-bar which carries the clamping-piece h, so that theslotted end of the said clamp-bar will be maintained in contact with thepin m of the cam-lever.

In order to adjust this clamping device to tables having tops of varyingthicknesses, I form a series of notches, 0, upon the clampbar, alongsideof the slot, so that when the cam-lever has been shifted to therequisite position in the slot the pin will fit into the notches at suchpoint, and hence determine the extent to which the cross-piece or jaw ofthe clamp-bar may be opened.

The board A is provided with elastic cushions 19, and the clamp-piece hwith an elastic cushion, q, so that when the board is clamped upon theedge of a table there will be no injury to the same.

, \Vhat I claim, and desire to secure by Letters. Patent, isy In aclamping device for securing ironingboards to table-tops, the bedpiece Oand the pivoted clamp-bar 6, formed with a slot, g, notches 0, formed inthe bar, and the cam-lever passed through the slot, and having the pin madapted tofit into the notches, as herein specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

EDWIN W. WARREN.
